Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
In figure: 1 is tourie, 2 for inhaling gold resin, and 3 is input pipe, and 4 is suction pump, and 5 is that gold reclaims water washing cylinder, and 6 is outlet tube.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
Referring to Fig. 1, capital retracting device, reclaiming water washing cylinder 5 and tourie 1 including gold, be provided with adsorption column in described tourie 1, be provided with suction gold resin 2 in this adsorption column, wherein, the ratio range of the height of adsorption column and the diameter of adsorption column is 8～10:1.Figure does not draw adsorption column.
Such as, the adsorption column diameter inhaling gold resin corresponding of 100 kilograms is 20 centimetres, and adsorption column height is 160 centimetres；The adsorption column diameter inhaling gold resin corresponding of 200 kilograms is 20 centimetres, and adsorption column height is 200 centimetres.
In the present embodiment, described adsorption column is two to six layers, stacked up and down.It is also preferred that the left adsorption column is four to six layers, stacked up and down.
Reclaiming water washing cylinder 5 from gold and carry the liquid come, driven by suction pump, liquid is carried from the lower end of adsorption column towards upper end.
It is connected by input pipe 3 between outlet and the import of tourie 1 of described gold recovery water washing cylinder 5, input pipe 3 is provided with suction pump 4.
It is additionally provided with activated carbon adsorption filter and cartridge filter between outlet and the suction pump 4 of described gold recovery water washing cylinder 5.
It is connected by outlet tube 6 between water return outlet and the outlet of tourie 1 of described gold recovery water washing cylinder 5.
The outlet that described gold reclaims water washing cylinder 5 is provided with a pH tester.
The outlet of described tourie 1 is provided with the 2nd pH tester.
By the initial count to a pH tester and the 2nd pH tester, and the comparative analysis of the monitoring counting in removal process, can be determined that suction gold process, thus deciding whether that changing gold reclaims the liquid in water washing cylinder 5 and whether change adsorption column and inhale gold resin 2.
Wherein, activated carbon adsorption filter is employing graininess cocoanut active charcoal GAC absorption chlorine residue is usual and maximally efficient method.Its principle is to utilize its porous solid material, the free chlorine in main elimination water, can also adsorb the impurity such as Organic substance in water, colloidal particle, microorganism, stink simultaneously.Active carbon adsorber configures high performance PVC butterfly valve and controls, stable and reliable for performance.
Cartridge filter is configured with filer element type cartridge filter, and the minimum requirements in its aperture is less than 10 μm, it is prevented that particle that may be present, and generally it is last one of pretreatment, and business recommendations uses aperture less than or equal to 5 μm.
Inhaling gold resin is a kind of ball-type anion alkaline exchanger resin, and this resin has specific pore structure, its skeleton has specific strong, alkalescence group, there is multiple excellent characteristic, especially gold cyanide complexes is had special selectivity, be particularly well-suited to the recovery containing gold lean solution or waste liquid.
The adsorbance that suction gold resin in this utility model is applied in the industry is probably about 5%, and the saturated extent of adsorption inhaling gold resin can reach 8%-16%, mass ratio, and the gold content of the residual liquid crossed by the golden resin absorption of suction is minimum can reach 0.1-1.0 g ton.
The adsorption rate inhaling gold resin is fast, is more than five times of common coconut carbon adsorption rate.
The selectivity inhaling gold resin is better, to other metal ions, such as copper, nickel, ferrum and/or lead etc., annoyance level little.The antifouling property inhaling gold resin is better, it is possible to pure water or sodium chloride solution, it is carried out.
The scope of application inhaling gold resin is relatively wide, the absorption of the gold being mainly used in cyanide solution, it is also possible to suitable in the absorption to the gold dissolved acid solution even chloroazotic acid.Inhaling the condition of compatibility width of gold resin, the requirement of adsorption conditions pH value is not too harsh by it, pH value 1～12.
After inhaling gold resin absorption gold, the post-processing approach of Extracting Gold is relatively more, both can first carry out liquid desorbing and carry out pyrogenic process refinement again；Can also directly after carbonization high temperature burn, be directly refined into elemental gold granule, the response rate is higher.
The golden lean solution of super low concentration can being adsorbed, minimum gold solution concentration can reach 1PPM, so can carry out the ultralow golden lean solution of content and waste liquid reasonably reclaiming and utilizing, reduce unnecessary waste and loss.
It will can be different according to the concentration of gold-containing liquid, gold content in liquid is more high, adsorbance and adsorption rate can be more big, be 0.001 g/l i.e. 1 g ton, namely 0.001 kg/ton according to concentration, gold-containing liquid and adsorbance be 5% calculating, the suction gold resin of 100 kilograms can adsorb the gold of about 0.5 kilogram, namely altogether can processing the liquid of about 100 tons, the suction gold resin of 200 kilograms can adsorb the gold of about 1 kilogram, altogether can process the liquid of about 4000 tons.
Inhale gold resin 100 kilograms can process per hour 1 ton containing gold plating bath body, calculate according to this gauge, darg 8-12 hour, the treating capacity inhaling gold resin every day of 100 kilograms is 8-12 ton liquid, the treating capacity inhaling gold resin every day of 200 kilograms is 16-24 ton, by the 20 tons of calculating of the current Design Treatment amount of our company, gold recovery valency, by 300 yuan/gram, is namely transformed and can be realized year economic benefit 2,000,000 yuan/year after successfully.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
